I have learned how to work with TCP and UDP connections with the Java standard API but now I am trying to see how to create raw packets to send on a network with Java so that I can create the header info and everything. I tried getting jpcap but when I run the code I get access restriction errors and all sorts so I am wondering if there is somethng else I should use and if not how would I fix those errors. Thanks in advance for any help.
